An image display device includes: a first power supply line; a second power supply line; a plurality of pixel circuit; a driving circuit for supplying a data signal and a scanning signal; and a switch unit. Each pixel circuit includes: a driving transistor between the first power supply line and the second power supply line; a light emitting element controlled by the driving transistor; and a storage capacitor for storing the data signal and controlling the driving transistor. The driving circuit causes the storage capacitor to store the data signal and controls an intensity of light emission based on the data signal. The switch unit is provided at one of one end of the first power supply line and one end of the second power supply line to control whether or not to allow a current to flow from the first power supply line to the second power supply line.
